You should take Vitamin C when raising your glutathione with Immunocal or other methods for raising glutathione because Vitamin C is an essential co-factor for production.
Here is a sum up of what Dr. Jimmy Gutman has to say on the subject:
Vitamin C: Also known as ascorbic acid, this is probably the best known water soluble vitamin. Most living organisms can make their own Vitamin C, but humans cannot, so it must be supplemented.
Vitamin C has been the subject of medical studies regarding it's role as an antioxidant for many years now.
Vitamin C has a key role in glutathione metabolism. It is involved in the glutathione enzyme system which keeps Vitamin C, Vitamin E, and other antioxidants in their reduced state.
This preserves their ability to keep on working as antioxidants in the body, effectively recycling them and making them work over and over again before being disposed of by the body.
There have been many studies showing that Vitamin C supports and raises glutathione levels and activity. By the same token, when there is not enough glutathione, Vitamin C is far less effective and rapidly depleted.
So we can see why they go hand in hand with one another. There is much controversy over the adequate dose of Vitamin C needed. If glutathione levels are adequate, than 200-1,000 mg/day should be sufficient.
